The present invention relates to improvements in frame constructions for doors or windows, i. e. in the construction of sash frames or fixed door or window frames. One object of the invention is to provide a frame construction, in which the sections forming the frame are of simple shape and may be manufactured at low cost, and in which the frame has small weight. A further object is to provide .a sash frame in'which a glass plate may be fitted in a simple and efficient manner. The frame construction according to the invention, which comprises L-shaped metal sec tions, is principally characterized in that the frame members comprise open L-shaped sheet metal sections having one leg of the L disposed perpendicularly to the door or window plane and the other leg directedtowards "the-spacebetween a sash frame and an adjacent sash frame or an adjacent door or window frame cooperat ing therewith, the sheet metal of said other le being bent over at least 180 at the free longitudinal edge of said leg and adapted to cooper-1- ate at said bent and thereby strengthenedportion of said other leg of the open L-shaped'sheet metal section with said adjacent frame, preferably through the intermediation of a packing.

The above mentioned and other objects and features of the invention are further disclosed in the following description of some embodiments of the invention illustrated by way of example on the accompanying drawings, in which:

Fig. 1 is a perspective frontview of a window according to the invention, Fig. 2 a section on line 11-11 in Fig. 1, and Fig. 3 a section on line IIIIII in Fig. 1. Fig. 4 is a front elevation of an espagnolette and Fig. 5 is a side view of the lower end of said espagnolette. Figs. .6 and 7 are cross sections illustrating modifications of the l frame sections used in the frame construction illustrated in Figs. 1-3.

In Figs. 1-3 I designates a wall having a stationary frame provided therein. The stationary frame comprises a small sheet metal section 2, v

3 at the inner side of the windowand a substantially L-shaped sheet metal section 4, 5, which is heat insulated relatively to the first mentioned gether with the leg 5 a channel opening towards their edges are embedded in packings 25.

theleg 4. At the inner side of the leg 3 of each vertical frame section 2 3 a recess Ill is provided in the Wall to accommodate one part II of a hinge II, l2 extending through a suitable opening in the leg 2 of the sheet metal section 2, 3.

The part I I is spot welded to the leg 3. However. it may naturally be riveted or bolted thereto, if desired.

The movable window frame or sash comprises substantially L-shaped sheet metal sections I3, and I5, I6 and band-shaped sheet metal sections I1 and I8 provided with grooves for packings 8. The legs I3 and I5 of the L-shaped sections, which are parallel to the window plane,

1 are bent over or double folded at their free ends in similarmanner as the legs 5 of the stationary frame sections 4, 5 so that ribs I9 and 2B, respectively, directed towards the interior of the respecg tive frame section are formed. The ribs 9, I9

I and 20 of the stationary frame sections and the sash sections, respectively, are adapted to cooperate with the packings 8. The part 12 of each hinge II, I2 is inserted through the leg it of the vertical section I3, I4 and secured to said section through spot welding or in any other suitable manner. The legs I3 consequently show a completely smooth surface at the inner side of the window and the hinge parts I2 are substantially concealed in the interior of the sections. The legs 14 and I6 are folded some at 2| and 22, respectively, forming a fold. extending along the frame and producing one wall of a seat necessary for fitting the glass plate. The glass plates 24 are fitted between said fold and strips 23 and Also the band-shaped sheet metal sections I! and I8 are multiple folded so as to form folds 26 and 21, respectively, between which and strips 23 secured to the sections the glass plates 24 and their packings 25 are secured. The strips 23 may be secured to the sections by means of spot welding. The frame sections I3, M and il forming the vertical side members of the window sash are connected by means of hinges 23. The central vertical sections I3, l4 and I1, and I5, IE and I8, respectively, are connected to each other by means of clasping means 29 of any suitable type. The space between the sections l5, I6, 18 of the left window in Fig. 3 and the sections !3, I4, I! of the right window may preferably be utilized for accommodating espagnolettes or other means necessary for operaitng the window. In Fig. 3 locking rods 30 are provided in the interior of the leg I3 of the central vertical section of the inner right window. Each rod 30 is provided with a toothed rack 31 at one end, which cooperates with a gear 32 provided on a shaft 33 of the operating handle 34, as illustrated in Figs. 3 and 4. At the upper and lower ends of the rods 30 fingers 35 are provided, as illustrated in Figs. 2, 4 and which may engage pins 36 provided on brackets 31 welded to the stationary frame. Drip plates 38 are welded to the lower sash members I I of the outer windows.

In the above described coupled double window the inner and outer surfaces of the window frame sections are smooth and of simple shape, and the hinges, espagnolettes or the like are substantially concealed in the interior of the frames. The above described frames may be made from sections forming the inner frame as well as the outer frame of a door or window, and said frames may be divided in the door or window plane, for instance after securing the hinges or other connecting means so that the inner and outer frames may be swung apart. Thus, the sections l3, l4 and I1, and I5, I6 and I8, respectively, may before the division in the window plane be connected at their adjacent edges.

The above described frame construction according to the invention may naturally be modified in several different ways, and the invention may, for instance, also be applied to plain or single doors or windows. The folding, bending or the like of the sheet material of the sections for forming the fold or seat for the glass plate may be carried out in different ways. The 180 folding or bending of the sections may, for instance, comprise an arcuate bend, or two 90 bends, as illustrated at 2| and 22 in Figs. 2 and 3, or one 180 bend, as illustrated at 39 and 40 in Fig. 6, which shows a modified frame section according to the invention. In this case the frame section 4!, 42 is connected to the outer frame section 43 by means of a hinge 28 in the sam way as the sections l3, l4 and I1 in Fig. 3. The l80 fold 40 is continued by a further fold 44 between which and strips 23 the glass plate 24 and its packing 25 are secured in the manner above described. The leg 4| is triple folded at 45 to make the section more rigid. Fig. '7 illustrates a further embodiment of the invention, in which the band-shaped section 46 is provided with a 180 arcuate fold 41 forming a seat for the glass plate 24 and its packing 25 between which and the free edge of the fold 41 a suitable strip of soft material 48 may be provided. The L-shapecl section 49, 50 is folded substantially in the same way as the sections I3, l4 and l5, IS in Fig. 3 but the legs 46 and 50 of the two sections may in this case be folded twice at 5| and 52 to form the inner walls of the seat for the glass plates 24 so that the strips 23 or putty strips or the like may be dispensed with. The sections 46 and 49, 50 may be connected by a hinge 53'. Obviously the folds 39 and 40 or 2|, 22, 25, 21 may have the same arcuate shape as the fold 41.

It is to be understood that the embodiments of my invention hereinabove described have been given merely by way of illustration and do not constitute a limitation of the scope of my invention, which is to be determined by the appended claims.
